Whether you want to work remotely, hear from friends and family or simply move to a new city while travelling, a stable internet connection is essential. In this post we talk about eSIMs, explaining what they are and how they work and adding some practical tips on how to make the most of this option when travelling abroad.
What is an eSim
The eSIM is a virtual SIM integrated directly into the smartphone that eliminates the need to insert a physical SIM but retains identical functionality. Thanks to this technology, it is possible to activate a local data plan and connect to a mobile network simply via software.
Configuration and Activation
The steps to purchase and use an eSIM are simple.
Once you have chosen the operator, simply go to the site, select the destination, the type of data package you want to activate and its duration, and specify the date on which it will be activated.
To configure an eSIM, simply use the QR code containing the virtual SIM data. This code must be scanned directly with the camera of the device to be configured, following the instructions. Some eSIM providers give the possibility to install it directly via their application.
Once you arrive at your destination, simply activate your eSIM and you will have a second data plan and access to the Internet connection. It is advisable to read the instructions on the site where you will purchase your eSim. In our case, we had to change a couple of parameters in the phone’s settings in order not to incur additional costs once we arrived at our destination.
Pros and cons of eSIMs
The international eSIM is not always the best solution, so it is fair to consider whether its purchase for your next trip abroad is an appropriate solution.
Here are the advantages of buying an eSIM:
- Global coverage: Provides access to mobile networks in virtually every part of the world, ensuring that you can stay connected anywhere. Depending on the operator chosen, the international eSIM will choose which network to hook into in the foreign country, so the connection quality is the same as if you bought a local SIM.
- Easy operator switching: You can easily switch from one operator to another, choosing the tariff plan that best suits your travel needs.
- Eliminating the problems associated with physical SIM cards: Connectivity is secure and guaranteed directly on the device. In addition, you can leave your national SIM in the phone, so that you can continue to receive calls from Italy should you need to.
- Simplicity. Activating an international eSIM is quick and easy. From purchase to activation will not take you more than a few minutes.
The disadvantages of international eSIMs, while relatively limited compared to the advantages, include the following:
- Limited availability and compatibility: Not all mobile devices support eSIM technology, and this may limit your ability to use them. Always check if your device is compatible;
- High costs for long stays: the international eSIM does not have a standard cost. As the period of use increases, the costs may become high. In these cases, buying a local SIM may be more cost-effective;
- Not always wi-fi hotspots: International eSIM operators generally do not allow the use of the network to generate hotspots. Check whether your operator allows this functionality.

Alternatives to eSIMs
As an alternative to the use of eSIMs, there are several possibilities that can be used depending on travel needs. Below are the alternative solutions for having Internet connection on your phone while on holiday:
- Activating a data offer with your operator is an option offered by all major Italian telephone operators with specific packages for using the Internet abroad. These options are not always available for all countries and may not be convenient, but they are worth considering;
- Renting a portable Wi-Fi router is a popular solution n many destinations (we did it in Japan). These devices (about the size of a phone or less) act as modems and allow multiple devices to connect to their Wi-Fi network. They are lightweight, space-saving and offer a secure connection, but often come at a high cost;
- Buying a localSIM with a local data plan is generally cheaper than the offers of Italian operators. Although it only allows the connection of one device, it is possible to use the smartphone’s hotspot function for sharing. The only drawback is the need to physically insert the SIM into the phone, forcing one to remove one’s own (temporarily giving up one’s number) or to carry a second smartphone.
